General Description

The MAX3370/MAX3371 logic level translators are ideal

for applications interfacing low-voltage devices to other

logic levels. Externally applied voltages set the logic

levels of the MAX3370/MAX3371. The devices accept

allowing data transfer between low-voltage ASICs and

higher voltage devices. The MAX3371 features a shut-

down mode that reduces supply current to <1µA and

puts the I/O pins in a high-impedance state.

The MAX3370/MAX3371 are bidirectional level shifters,

operate at speeds up to 2Mbps with an active driver

and up to 500kbps with an open-drain driver.

The MAX3370/MAX3371 are available in space-saving

5-pin and 6-pin SC70 packages, respectively.
